A:  This is true.  They are not growing.   The ground is cold and roots will not start to grow until the soil warms--which will be approximately mid-March.  Some of the older leaves will fall off and new leaves will form with warm spring temperatures.

A: Light pruning may be done year-round.   The long new shoots may be trimmed back leaving approximately 6 inches from the rest of the foliage.  Wherever a branch is cut, 2 -3 new branches will then start.   This increases the weight of the citrus shrub but more importantly provides more shade for the bark and fruit.

A:  Recommended fertilization is the first part of March.  Our desert will sometimes surprise us with a freeze (significant high in the 20s) in the first 2 weeks in February.  If fertilization occurs now and the new shoots develop, then a burn-back will occur.  For citrus fertilizer amounts go to our fertilization page.

Deciduous trees - these trees are just starting to awaken.  When they are dormant they require no water, once they leaf out, watering can begin.  Fertilizing these trees in January is recommended and then again following fruit harvest.  The fertilization technique is the same as for citrus.
